Detailed explanation-1: -The water is absorbed by the root hair and undergoes cell to cell movement by osmosis until it reaches the xylem. This water is then transported through the xylem vessels to the leaves and is evaporated by the process of transpiration.

Detailed explanation-2: -The process of transpiration involves osmosis. This is because the water moves from the xylem cells to the mesophyll cells. Evaporation and diffusion occurs in order to aid transpiration.

Detailed explanation-3: -Osmosis is the process of movement of water molecules from the region of higher concentration into the region of lower concentration. This mechanism or process helps in absorption of water from the soil by the roots of a plant.

Detailed explanation-4: -Osmosis is the process by which water molecules move from a weaker solution into a stronger solution through a partially permeable membrane. It occurs between cells. Transpiration is the loss of water in vapour form from the leaves into air. It occurs when water is released into air.

Detailed explanation-5: -Transpiration is the evaporation of water from the spongy mesophyll cells followed by the diffusion of water through the air spaces and out of the stomata .
